New to this edition are animation tutorials written exclusively for Horizons by text author Mike Seeds. These tutorials will help students review important concepts and explore topics from the textbook in more detail. Each tutorial requires a student to consider or manipulate an animation in order to answer a series of questions. Hints are offered with each step, which encourages students to think through each question. Animation tutorials will build student reasoning so they will ultimately be able to draw conclusions.

Questions Available within WebAssign

Most questions from this textbook are available in WebAssign. The online questions are identical to the textbook questions except for minor wording changes necessary for Web use. Whenever possible, variables, numbers, or words have been randomized so that each student receives a unique version of the question. This list is updated nightly.
